3.5.7.21 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Linus Torvalds <[email protected]> commit 3c0b9de6d37a481673e81001c57ca0e410c72346 upstream. I think we could just move the full vm_iomap_memory() function into util.h or similar, but I didn't get any reply from anybody actually using nommu even to this trivial patch, so I'm not going to touch it any more than required. Here's the fairly minimal stub to make the nommu case at least potentially work. It doesn't seem like anybody cares, though.
